Question
Which statement below is TRUE?
1)The percentages of genes related to protein synthesis and DNA replication are highest in organisms with smaller genomes, whereas in larger genomes, the percentage of transcriptional regulatory genes is greatest.
2) The percentages of genes related to protein synthesis and DNA replication are highest in organisms with larger genomes, whereas in small genomes, the percentage of transcriptional regulatory genes is greatest.

Explanation / Answer
First one is True
The percentage of genes involved in protein synthesis is much higher in organisms with small genomes compared to those with larger genomes. In larger genomes, transcription and two-component signal
transduction genes are much higher than in smaller genomes. It is because the protein synthesizing apparatus cannot be dispensed, whereas regulatory proteins are not essential and are often
specialized thus only exist in larger genomes. The smaller the genome, the larger fraction will be protein synthesis genes.
